Crafting my Fellowship Personal Statement was like weaving the threads of my aspirations into a tapestry of words. Each sentence became a brushstroke, painting a vivid portrait of my journey and ambitions. Beyond being just a document, it became a mirror reflecting the depth of my experiences. Like a conductor guiding an orchestra, my personal statement was composed to resonate with my unique voice. In the realm of specialized opportunities, this statement serves as a compass, guiding me toward the next chapter of my professional growth. With each word, I felt the guidance of mentors shaping my story into an eloquent narrative.

Post by ojz0r on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Its important that you know the difference between the two. Example 1: Coils[0] := Coils[0] OR (Buttons[0] AND Sensors[0] > 6); In this case the statements will be evaluated every scan and result in either true or false for Coils[0]. Example 2: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; END_IF In this example Coils[0] will latch the result in a true evaluation, if you want it to behave the same way as example 1 then you need to do it like example 3 below: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; ELSE Coils[0] := FALSE; END_IF However back to the real question. There is no problem using either example 1 or example 3, if im not requiring a latch i usually go with example 1 as it is more compact.

Thank you for the reply. I got an error saying that MEM.PackBytesToWord(GVL.Actual_Speed_DUT_high,GVL.Actual_Speed_DUT_low) = u; is not a valid statement. Am I missing some library?

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

Post by trusty-squire on parker servo and position ^{CODESYS Forge talk (Post)}
@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Post by fredashbolt on Dynamically Update JSON Payload ^{CODESYS Forge talk (Post)}
I am trying to generate a JSON payload populated with a value that updates for use with a telemetry system, the payload is to be published by MQTT. I have established the MQTT client and can publish a working JSON payload but I can't get the payload to update as the value (iValue) changes. I am using a timer to trigger the .SetValue function periodically, but the JSON will only give the value as it is when it is first initialized using xFirst IF statement. Any suggestions? Thanks VAR pJsonData : POINTER TO JSON.JSONData := factory.Create(); fb_JBuilder : JSON.JSONBuilder; diRootIndex, diObject1Index : DINT; iValue : INT := 10 ; jsonArrayWriter : JSON.JSONByteArrayWriter; wsJsonData : WSTRING(1000); xFirst : BOOL := TRUE; utf8JsonData : STRING(2000); diTempVal : DINT ; PublishTimer : TON ; END_VAR IF xFirst = TRUE THEN fb_JBuilder ( pJsonData := pJsonData , diRootObj => diRootIndex ) ; diObject1Index := fb_Jbuilder.SetKeyWithObject ( "Device" , diParentIndex := diRootIndex ) ; diTempVal := fb_Jbuilder.SetKeyWithValue ( "Temp" , iValue , diParentIndex := diObject1Index ) ; xFirst := FALSE ; END_IF PublishTimer ( IN := PublishTimer.Q = 0 , PT := T#5S ) ; IF PublishTimer.Q THEN fb_JBuilder.SetValue ( iValue , diTempVal ) ; END_IF jsonArrayWriter( xExecute := PublishTimer.Q , pwData := ADR(wsJsonData), udiSize := SIZEOF(wsJsonData), jsonData := pJsonData^, xAsyncMode := FALSE ) ; JSON.Stu.ConvertUTF16toUTF8( ADR ( wsJsonData ) , ADR ( utf8JsonData ) , SIZEOF ( utf8JsonData ) , bStrictConversion := TRUE ) ;
